DAVID S. KENNEDY, OF BROOKLYN, NEW YORK, ASSIGNOR TO MERGENTHALER LIN OTYPE COMPANY, A CORPORATION OF NEW YORK.

TYPOGRAPHICAL MACHINE.

Specification of Letters Patent.

Patented near, 1914'.

Application filed November 29, 1913. Serial No. 803,689.

To all whom it may concern Be it known that I, DAVID S. KENNEDY, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Typographical Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to typographical machines, such as linotype machines of the general organization represented in Letters Patent of the United States, No. 436,532, to O. Merge-nthaler, wherein circulating matrices are released from a magazine in the order in which their characters are to appear in print and then assembled in line, the composed line transferred to the face of a mold, the mold filled with molten metal to form a slug or linotype against the matrices which produce the type characters thereon, and the matrices thereafter returned through distributing mechanism to the magazine from which they started.

More particularly, it relates to a special form of matrix, and to means for handling a line of matrices, whereby the regular assortment of the machine may be supplemented by additional characters or faces at the will of the operator. p 4

In the accompanying drawing, I have shown my invention as applied to a style of matrix formed with a very large character, such as is used for instance in advertising matter, etc.; and I have shown such a matrix, or a line thereof, in operative relation to the casting mechanism, at which time it is supported in the first elevator at one side only and has its opposite side wholly exposed and adapted to cooperate with the mold. While these features embody the preferred form of my invention, it will be understood that many changes. and var1a-- tions may be made therein, and in its mode of application, which will stlll becomprlsed within its spirit. Generally speaking, I desire it to be understood that I do not limit myself to any specific form or embodiment,

. except in so far as such limitations are specified in the claims.

In the drawing: Figure 1 is a vertical section through the first elevator, mold, pot mouth, etc. illustrating the means for hold ing the matrices in casting position; and

Figs. 2, 3 and 4 are respectively edge, side, 2nd perspective views of my improved ma- The matrix is of the general contour and style of the ordinary linotype matrix except in the particulars now to be mentioned. It should be first noted that the front upper ear thereof is cut away, thereby materially increasing the length, of the front edge, and permitting the formation therein of a very large or extended character Y, which is of considerably greater height than any that can be now formed-on 2 and 3 illustrate by dotted lines the comparative contour of the ordinary matrix and indicate the position thereon of the distributing teeth and front ear, which'are omitted in my special form. The-rearside is vided with the customary depression W between the upper and lower projecting ears.

Referring to Fig. 1, the matrices X are presented by the elevator A to the mold B,

into which molten metal is delivered in the usual manner from the pot mouth C. In the present instance it will be observed that both the mold and pot mouth are suitably enlarged to cooperate with the extended character on the matrices. nlike the commercial form now in use, the elevator A is not provided with the parallel rear wall or extension, and the matrices are supported therein by the engagement of its rib ,D in the depression W below the upper ear, the matrices being held in proper relation thereto by the further engagement of the overhanging rib E of the elei'ator in the previously mentioned transverse cuts or notches Z. Y

This arrangement not only serves to support the line of matrices securely in the first elevator, but also leaves its front or operative side'wholly exposed, in order that it may coiiperate freely with the mold, and so that when the parts'are in their casting relation they will be firmly held therein.

It should also be noted that this arrangement may similarly-be employed in connection with matrices of different construction from that herein specifically illustrated.

As already stated, I have shown my invention only in preferred form and by way of example, and as. adapted to a linotype machine, but obviously many modifications and alterations therein, and in its mode of adaptation, will suggest themselves to those skilled in the art, without departure from its scope.

Having thus described my invention, its construction'and mode of operation, what I claim and desire to secure by Letters Patent of the United States, is as follows:

1. In a typographical machine, the combination of a line of matrices, and a mold to cooperate therewith and having a slot of such width as to cover the greater portion of the front side of the line, the said matrices being free from projecting ears at their upper ends on their edges adjacent the mold to permit of their cooperation with the mold.

2. In a typographical machine,-the combination of a line of matrices, and a mold to cooperate therewith and having a slot of such width as to cover the greater portion of the front side of the line, the said matrices having one of their edges longer than the other to permit of their cooperation with the mold.

3. In a typographical casting machine, the combination of a mold, and the first elevator mounted to move to and from the mold, the said elevator being provided with a rail to sustain the rear side only of the matrix line, and further with a rib or proarrears jecticn to maintain the matrix line upon the rail, the said rib being arranged so as to leave the front side of the matrix line wholly exposed. 5

i. In a typographical casting machine, a device to carry the matrix line to and from casting position, and formed with a supporting rail to sustain therear side only of the matrix line, and with further means to maintain the matrix line in position upon said rail, the said means being arranged so as to leave the front side of the matrix line wholly exposed.

In a typographical casting machine,

the combination of a line of matrices, each formed with a notch in its upper end, and a support therefor said support being formed with a supporting rail to sustain one side only of the line, and further with a rib to engage in the notches of the matrices and maintain them in position upon said rail.

6. In a typographical casting machine, the combination or a line of matrices, each formed on one edge only with a supporting ear, and a support for said line movable to and 'from casting position, said support being formed with a rail to stain the matrices by their supporting ears and with arib or projection to engage the matrices between their edges so as to prevent their dislodgment from the sustaining rail.

In testimony whereof I have affixed my signature in presence of two witnesses.

DAVID S. KENNEDY.
